Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

It should be noted that when a component/part is referred to as being "disposed on" another component/part, it can be directly on the other component/part or intervening components/parts may also be present. When a component/part is referred to as being "connected/coupled" to another component/part, it can be directly connected/coupled to the other component/part or intervening components/parts may also be present. The term "connected/coupled" as used herein may include electrical and/or mechanical physical connections/couplings. The term "comprises/comprising" as used herein refers to the presence of features, steps or components/features, but does not preclude the presence or addition of one or more other features, steps or components/features. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Referring to fig. 1 to 4, an auxiliary tool for installing an expansion bolt kit includes a casing body 1, a stepped hole 3 penetrating through two ends of the casing body 1 is formed in the casing body 1, the stepped hole 3 includes an upper hole 31 and a lower hole 32, the diameter of the upper hole 31 is smaller than that of the lower hole 32, the lower hole 32 is adapted to a casing exposed outside the expansion bolt kit, the length of the lower hole 32 is the same as that of the casing exposed outside the expansion bolt kit, a limit screw 2 is further disposed on the upper portion of the casing body 1, and the limit screw 2 is perpendicular to the upper hole 31 and can extend into the upper hole 31.

The sleeve body 1 comprises an upper pipe body 11 and a lower pipe body 12, wherein the cross section of the upper pipe body 11 is polygonal or circular, and the cross section of the lower pipe body 12 is circular. The upper tube 11 and the lower tube 12 may be integrally formed, and the cross section of the upper tube 11 is preferably polygonal, so that when the expansion bolt set is installed, manual screwing is convenient even if no electric screw screwing tool is provided.

The limiting screw 2 is at least one, is arranged on the upper pipe body 11, is preferably two, and is symmetrically arranged on the upper pipe body 11, so that tools such as a screwdriver bit and the like are assembled and are more stable.

The upper hole 31 is a polygonal hole or a circular hole, the lower hole 32 is a polygonal hole or a circular hole, the shape of the lower hole 32 can be selected according to the shape of the expansion bolt suite, the upper hole 31 is preferably polygonal, can be matched with the screwdriver bit, and can drive the sleeve body 1 to rotate when the screwdriver bit rotates, so that abrasion to the limit screw 2 is prevented.

When the expansion bolt is used specifically, the limiting screw 2 is opened, the bit for screwing the expansion screw rod is arranged in the upper hole 31, the limiting screw 2 is screwed up again to correspond to the limiting groove on the bit to limit the forward and backward movement range of the bit, the expansion bolt sleeve is inserted into the reserved hole of the wood board, the lower hole 32 is sleeved in opposite to the expansion bolt sleeve, the expansion screw rod is smaller than the upper hole 31, the expansion sleeve is larger than the upper hole 31 and smaller than the lower hole 32, so that the expansion screw rod can be sleeved into the upper hole 31 from the lower hole 32 to be in contact with the bit correspondingly, the expansion sleeve can only be positioned in the lower hole 32, the expansion sleeve positioned in the lower hole 32 cannot be completely arranged in the lower hole 32 because the expansion screw rod is abutted against the bit, and when the bit is rotated and the expansion screw rod is driven to be pushed previously, the expansion sleeve can be slowly and completely arranged in the lower hole 32, until the expansion sleeve is completely installed in the lower hole 32, the lower pipe body 12 cannot be pushed forward due to the block of the wood plate, the bit cannot push the expansion screw further, and the expansion screw is just installed in place.

The utility model can limit the position of the tool for twisting the expansion screw rod by arranging the limit screw 2, and prevent the expansion sleeve from being damaged excessively when the expansion screw rod is twisted to influence the installation effect; by providing the stepped bore 3 with the stepped bore 3 comprising an upper bore 31 and a lower bore 32, the lower bore 32 accommodates the exposed portion of the expansion shell, avoiding over-installation or under-installation during installation.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
