In one embodiment, the base 10 has a channel 11, the connecting plate 20 is slidably fitted in the channel 11, and the connecting plate 20 abuts against the inner wall of the channel 11 to limit the position of the connecting plate 20 in the clamping direction of the clamping mechanism. In the present embodiment, the sliding portion of the connecting plate 20 is slidably disposed in the channel 11, so that the base 10 can be slidably engaged with the clamping mechanism. Through inserting connecting plate 20 in the passageway 11 of base 10, can utilize connecting plate 20 to realize spacing between clamping mechanism and the base 10, replace original bolted connection, realize the installation between clamping mechanism and the base 10 through the mode of plug, effectively improve the installation effectiveness, reduce the installation degree of difficulty.

The connecting plate 20 here closely laminates with the inner wall of passageway 11 and carries out spacing two kinds of circumstances including at least as follows with connecting plate 20 in the clamping direction of fixture, and one of them condition is, forms the tight fit between the slip lateral wall of connecting plate 20 both sides and the sliding fit lateral wall of passageway 11, utilizes frictional force to realize spacing connecting plate 20 in the clamping direction of fixture, in this embodiment, forms the tight fit between the lateral wall of connecting plate 20 and passageway 11 to guarantee the cooperation relation between connecting plate 20 and the passageway 11.

In another case, the connecting plate 20 has an insertion portion that is in insertion fit with the channel 11, and in the clamping direction, an insertion surface of the insertion portion is tightly attached to an inner wall surface of the channel 11 to form a press fit, so that the base 10 is limited to the connecting plate 20 in the clamping direction of the clamping mechanism.
