Detailed Description

Referring to fig. 1, fig. 1 is a cross-sectional structural view of a height adjusting mechanism of a positioning pin according to the present invention. The utility model discloses a positioning pin height adjusting mechanism which comprises an adjusting plate 1, a positioning pin 2, a mounting seat 3 and a fixing block 4.

The adjusting plate 1 is arranged in a sliding manner and is provided with at least one sliding groove 11. A guide post 13 is fixedly mounted on the adjusting plate 1 through a screw, and the guide post 13 guides the sliding direction of the adjusting plate 1. In this embodiment, two positioning holes are formed on the foot plate, so that two parallel sliding grooves 11 are formed on the adjusting plate 1 at intervals.

At least one positioning pin 2 is provided, one end of the positioning pin is provided with a sliding column 21, and the sliding column 21 is slidably arranged in the sliding groove 11 and drives the positioning pin 2 to slide along the height direction.
