The dismounting process of the mounting seat 1 and the connecting rod 2 is as follows:

as shown in fig. 6 and 7, the positioning assembly is first axially installed in the inner cavity of the connecting rod 2, so that the corresponding first limiting posts 5.1 on the two first connecting plates 5 protrude out of the side wall of the connecting rod 2, then the connecting rod 2 and the mounting seat 1 are axially assembled, when assembling, the protruding second limiting posts 5.1 on the two side walls of the connecting rod 2 are pressed inward by hands until the outer end face of the first limiting post 5.1 is flush with the outer end face of the connecting rod 2, then the connecting rod 2 is inserted into the mounting cavity 3 of the mounting seat 1, and the connecting rod 2 is pushed axially, when the first limiting posts 5.1 on the connecting rod 2 and the mounting holes 3.1 on the side wall of the mounting cavity 3 are moved to correspond, under the elastic action of the connecting portion, the two first connecting plates 5 move towards the separating direction, so that the first limiting posts 5.1 on the two first connecting plates 5 protrude and fit into the mounting holes 3.1 on the mounting cavity 3, thereby realizing the quick connection of the connecting rod 2 and the mounting seat 1. During the dismantlement, the tip of the first spacing post 5.1 of 3 lateral walls both sides of installation cavity is pressed inwards to the same hand earlier, and when losing the limiting displacement back of first spacing post 5.1 when the outer tip of first spacing post 5.1 and the outer lateral wall parallel and level of connecting rod 2, connecting rod 2 can realize the axial with installation cavity 3 and throw off.

In other embodiments, the positioning assembly may also be a structure installed on the mounting seat, for example, a clamp structure is sleeved on the outer side wall of the mounting cavity 3 of the mounting seat 1, and when one end of the connecting rod 2 is inserted into the mounting cavity 3, the stability of connection between the two is increased by the clamping effect of the clamp.

In another embodiment, the positioning assembly may also be a two-part snap fastener, wherein one part is fixedly connected to the mounting seat 1, and the other part is fixedly connected to the connecting rod 2, and when the two parts are assembled in the axial direction, the two-part snap fastener is snapped together, so that the stability of the connecting structure of the connecting rod 2 and the mounting seat 2 can also be improved.

In addition, in other embodiments, the detachable structure of the mounting seat 1 and the connecting rod 2 may also be: be equipped with the grafting pipe in the one end of mount pad 1, be equipped with the spliced eye in the one end that connecting rod 2 is close to mount pad 1, will peg graft in the spliced eye of pipe cartridge cooperation in connecting rod 2 one end during the installation, realize portable mounting means between them equally. Under the condition of the connection mode, the positioning assembly can also be in the form of a positioning bolt, after the insertion pipe is matched with the connecting rod 2 in a plug-in mode, the positioning bolt is radially inserted into the side wall of the connecting rod 2, the positioning bolt penetrates through the side walls of the connecting rod 2 and the insertion pipe, when the positioning bolt is required to be detached, the positioning bolt is firstly pulled out, and the axial separation of the insertion pipe and the connecting rod can be realized.

After setting up like this, when connecting rod 2 and installation cavity 3 along the endwise slip cooperation, have better guide effect and circumference limiting displacement, because the existence of the protruding 2.2 structures in location, circumferential direction's the condition can not take place between connecting rod 2 and the installation cavity 3, connection structure stability more.

On the other hand, because the connecting portion between two first mounting panels 5 is elastic, two first mounting panels 5 have the trend of outwards popping out when two first mounting panels 5 both sides do not have the circumstances of binding power, so when the installation, in order to guarantee that first spacing post 5.1 on two first mounting panels 5 can with the accurate cooperation of the first locating hole 2.1 that corresponds on connecting rod 2, the symmetry is equipped with two guide chute 2.3 on the lateral wall of the inner chamber of connecting rod 2, first locating hole 2.1 is established in guide chute 2.3. After setting up like this, when the locating component that two first mounting panels 5 are constituteed in the installation, the first spacing post 5.1 of two evaginations can push up and lean on the removal of direction spout 2.3, when removing to corresponding with first locating hole 2.1 position, and the outer terminal surface of each first spacing post 5.1 can be quick stretch out in first locating hole 2.1, improves the installation effectiveness.

Similarly, because the connecting rod 2 after the positioning assembly is installed has a convex first limit column 5.1 structure on the side wall thereof, and the installation cavity 3 is not convenient to install, the guide grooves 3.3 are symmetrically arranged on the inner side wall of the installation cavity 3 close to one end of the connecting rod 2, so that a certain guide effect is achieved, and the installation efficiency is improved.

Two second connecting plates 6 capable of moving relatively are further arranged in the inner cavity of one end, far away from the mounting seat 1, of the connecting rod 2, and the two second connecting plates 6 are connected through an elastic piece. In this embodiment, the connection structure of the two second connection plates 6 is the same as that of the two first connection plates 5. Of course, in other embodiments, the spring connection may also be directly between the two first connection plates 5.

On the other hand, at least one second limiting column 6.1 is respectively convexly arranged on the outer side wall of each second connecting plate 6, and second positioning holes 2.4 for the second limiting columns 6.1 to penetrate out are symmetrically arranged on the side wall of the connecting rod 2. In this embodiment, be equipped with two spacing posts 6.1 of second respectively on the surface of each second connecting plate 6, two second locating holes 3.2 are seted up respectively to corresponding symmetrical position on 2 lateral walls of connecting rod, improve the stability that follow-up handle coupling assembling and support handle are connected. In this embodiment, of the two second limiting columns 6.1, the protruding height of one second limiting column 6.1 close to the mounting seat 1 is higher than that of the other second limiting column 6.1, and when the mounting handle and the supporting handle are fixedly connected, one second limiting column 6.1 substantially far away from the mounting seat 1 plays a limiting connection role, and one second limiting column 6.1 close to the mounting seat 1 only plays an auxiliary unlocking role, that is, when the mounting handle and the supporting handle are mounted, the two second connecting plates 6 can be close to each other by pressing one second limiting column 6.1 close to the mounting seat 1, and the two second limiting columns 6.1 far away from the mounting seat 1 playing a fixing role are driven to slide in the corresponding mounting holes, so that the end of the supporting handle can be further pushed towards the mounting seat 1 until the second limiting columns 6.1 are mounted in the corresponding mounting holes on the supporting handle, thus, the protection function can be achieved, and the end part of the supporting handle is prevented from being injured in the axial sliding assembly process.

The foregoing has described preferred embodiments of the present invention and is not to be construed as limiting the claims. The present invention is not limited to the above embodiments, and the specific structure thereof is allowed to vary, and various changes made within the scope of the independent claims of the present invention are within the scope of the present invention.
