[0104] When the base plate 7 reaches the bottom of the groove, the L-shaped vertical fixing block 91 is pressed upward by the third compression spring 95, the L-shaped vertical fixing block 91 is disengaged from the clamping of the horizontal fixing block 93, and the horizontal fixing block 93 is pushed out under the action of the second compression spring 92, so that the base plate 7 and the bottom of the groove are more stably and accurately fixed. The positioning groove 96 on the side of the horizontal fixing block 93 close to the spring does not affect the placement into the bottom of the groove, in the initial state, the clamping rod of the L-shaped vertical fixing block 91 clamps the horizontal fixing block 93 in the outwardly extending state, which avoids the problem that the uneven bottom of the groove cannot effectively press the L-shaped vertical fixing block 91 and the horizontal fixing block 93 cannot be pushed out.
