Thread gauge capable of being screwed in from two sides

The thread gauge comprises a measuring head and a handle, a through hole penetrating through the two ends of the measuring head is formed in the middle of the measuring head, and the handle is detachably arranged on the end face, symmetrical about the through hole, of one end of the measuring head through connecting threads or detachably arranged in the middle of the through hole through a combined connecting piece. The gauge has the advantages that the screwing-in direction of the gauge can be freely selected, the machining difficulty is reduced, and production and use are facilitated. 本实用新型涉及一种可双面旋入的螺纹量规，包括测头和手柄，测头中部开设有贯穿测头两端的通孔，手柄通过连接螺纹可拆卸设于测头一端关于通孔对称的端面或通过组合连接件可拆卸设于通孔中部。本实用新型的优点在于：可自由选择量规的旋入方向，降低加工难度，利于生产和使用。
