the frame structure 12 includes a first rack plate 121 and a second rack plate 122 erected on the base plate 11 at an interval. It can be understood that the first bracket plate 121, the second bracket plate 122 and the bottom plate 11 enclose an accommodating space for accommodating the electric push rod, that is, one end of the electric push rod is fixed on the bottom plate 11, and the first bracket plate 121 and the second bracket plate 122 are located on two opposite sides of the electric push rod.

The first support plate 121 is sequentially provided with a plurality of first limiting holes 121a at intervals along the abutting direction of the electric push rod, the second support plate 122 is sequentially provided with a plurality of second limiting holes 122a at intervals along the abutting direction of the electric push rod, each second limiting hole 122a corresponds to each first limiting hole 121a one by one, and the limiting member 20 sequentially penetrates through the corresponding first limiting hole 121a and second limiting hole 122 a. It can be understood that the propping direction of the electric push rod is the height direction of the first supporting plate 121 and the second supporting plate 122, that is, when the limiting member 20 is slidably inserted into the corresponding first limiting hole 121a and the second limiting hole 122a, the distance between the limiting member 20 and the bottom plate 11 can be correspondingly adjusted, so as to adapt to electric push rods with different length specifications.

Illustratively, the first limiting holes 121a are equidistantly formed in the first support plate 121, and the second limiting holes 122a are equidistantly formed in the first support plate 121, and the distances between the first limiting holes 121a and the second limiting holes 122a are the same, so that the requirement that the limiting member 20 is arranged in parallel with the bottom plate 11 is met, and of course, the distance between the first limiting holes 121a and the distance between the second limiting holes 122a can be different, so that an included angle is formed between the limiting member 20 and the bottom plate 11, and the testing requirement of the electric push rod under special conditions is met.

Referring to fig. 2 and fig. 3, in an embodiment, the limiting member 20 includes a limiting plate 21, the auxiliary device further includes a limiting structure 30, and the limiting plate 21 is limited in the first limiting hole 121a and/or the second limiting hole 122a by the limiting structure 30. As can be appreciated, the limiting structure 30 serves to prevent the opposite ends of the limiting plate 21 from coming out of the first limiting hole 121a and/or the second limiting hole 122a, thereby improving the mounting stability of the limiting plate 21.

For example, the limiting structure 30 may be a hole-shaft matching structure, for example, a shaft structure is provided on the limiting plate 21, and a hole structure is provided at the hole wall of the first limiting hole 121a and/or the hole wall of the second limiting hole 122a, and when the limiting plate 21 penetrates the first limiting hole 121a and the second limiting hole 122a, the shaft structure enters the hole structure to complete the limiting.

Or, for example, the limiting structure 30 may also be an elastic structure capable of deforming, for example, a reed, specifically, the limiting plate 21 and the first limiting hole 121a and/or the second limiting hole 122a adopt clearance fit, that is, the limiting plate 21 can smoothly pass through the first limiting hole 121a and the second limiting hole 122a, the reed is respectively disposed on the corresponding positions of the limiting plate 21 and the first limiting hole 121a and/or the second limiting hole 122a, when the limiting plate 21 penetrates through the first limiting hole 121a and the second limiting hole 122a, the corresponding reed deforms to fill the clearance between the outer wall and the hole wall of the limiting plate 21, so as to complete the limiting action, and meanwhile, the limiting plate 21 can be disengaged from the corresponding limiting hole only by applying a reverse acting force.

Specifically, in one embodiment, the limiting plate 21 is a stepped plate structure, and the stepped plate structure is stepped towards the surface of the bottom plate 11, that is, the stepped plate structure has a plurality of stepped end surfaces with different heights, so that the limiting plate 21 can be applied to several electric push rods with similar specifications when the position of the limiting plate 21 is not changed, and the position of the limiting plate 21 needs to be frequently adjusted.

Exemplarily, as shown in fig. 4, the limiting plate 21 has a stepped plate structure and has two stepped end surfaces, so that when the two opposite ends of the limiting plate 21 respectively penetrate through the corresponding limiting holes and are fixed on the first bracket plate 121 and the second bracket plate 122, the two stepped end surfaces all face the bottom plate 11 and have different distances to the bottom plate 11, so as to be suitable for the electric push rod with two approximate length specifications, and in the implementation process, the position of the limiting plate 21 does not need to be adjusted.

Referring to fig. 1 and fig. 2, in an embodiment, the limiting structure 30 includes a wave bead 31 disposed on the limiting plate 21 and a positioning hole 32 opened on an inner wall of the first limiting hole 121a and/or an inner wall of the second limiting hole 122a, and the wave bead 31 is adapted to the positioning hole 32. It can be understood that the limiting plate 21 is provided with a mounting hole for mounting the wave bead 31, and the fixing structure and the spring are used to realize that the wave bead 31 is always partially higher than the surface of the limiting plate 21, and the positioning hole 32 corresponds to the wave bead 31. In the actual installation process, when the wave bead 31 enters the first limiting hole 121a and the second limiting hole 122a along with the limiting plate 21, the wave bead 31 first abuts against the hole wall of the first limiting hole 121a or the hole wall of the second limiting hole 122a and is in an unstretched state, until the wave bead 31 corresponds to the positioning hole 32, the spring in the mounting hole ejects the wave bead 31, so that a part of the wave bead 31 is ejected into the positioning hole 32. Similarly, when the limiting plate 21 needs to be pulled out of the first limiting hole 121a and the second limiting hole 122a, the dragging force drives the wave beads 31, so that the spring in the mounting hole is extruded, and the wave beads 31 can slide out of the positioning hole 32.

For example, two beads 31 are disposed on two opposite sidewalls of the position-limiting plate 21, and meanwhile, positioning holes 32 are disposed on an inner wall of the first position-limiting hole 121a and an inner wall of the second position-limiting hole 122 a. Of course, the beads 31 may be disposed on the top and bottom end surfaces of the position limiting plate 21, and similarly, the positioning holes 32 adapted to the first limiting hole 121a and the second limiting hole 122a are disposed at the corresponding positions.

Referring to fig. 1 to fig. 3, in an embodiment, the position-limiting member 20 includes a baffle 22 disposed at an end of the position-limiting plate 21, and a length and/or a width of the baffle 22 is greater than an aperture size of the first position-limiting hole 121a and an aperture size of the second position-limiting hole 122 a. It will be appreciated that the baffle 22 serves two functions: firstly, the limiting plate 21 is further prevented from being separated from the first limiting hole 121a or the second limiting hole 122a, and the connection stability of the limiting plate 21 is improved; secondly, be convenient for operating personnel pull limiting plate 21.

Referring to fig. 1 to fig. 3, in an embodiment, the position-limiting member 20 further includes an adapting block 23, and the adapting block 23 is detachably connected to a side of the position-limiting plate 21 facing the bottom plate 11. It can be understood that, the function of the adapter block 23 is to fill up the gap between the limiting plate 21 and the end of the electric putter, and further improve the limiting effect of the limiting plate 21 on the electric putter.

Meanwhile, the adapter block 23 can be detachably attached to the restriction plate 21 during operation.

For example, a sliding block is arranged on the adapting block 23, and a sliding groove is arranged on the limiting plate 21, that is, the adapting block 23 is fixed on the limiting plate 21 in a sliding manner. Or, the limiting plate 21 is provided with a plurality of threaded holes, and the adapting block 23 is connected to the corresponding threaded hole.

It can be understood that the limiting plate 21 is a metal plate made of iron, cobalt and nickel, and magnetically attracts the magnetic member 24 on the adapter block 23.

Referring to fig. 1, in one embodiment, the frame structure 12 further includes a top plate 123, and the top plate 123 is connected to ends of the first and second rack plates 121 and 122 away from the bottom plate 11.
