The invention can save the operation time, improve the working efficiency and has good use performance.

At present, the length and the shape of the cross screwdriver are fixed, the traditional cross screwdriver cannot be well matched with different environments for use in a narrow space or an irregular space environment, a gap between the traditional cross screwdriver and a screw is prone to falling off in work, the screw and the screwdriver are purely adsorbed by magnetic force in work, and the magnetic force is small and cannot meet the connection stability of the screw during rotation.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides the cross screwdriver based on screw thread anti-skidding positioning in a multi-space environment, and solves the problems that the traditional screwdriver is poor in capability of adapting to different working environments and poor in positioning stability between a screw and a screwdriver.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: a cross screwdriver used in a multi-space environment and based on thread anti-skid positioning comprises a driving main rod, an adjusting driving rod and a handle, wherein the bottom of the handle is fixedly connected with the adjusting driving rod, an adjusting inner groove is formed in the top end inside the driving main rod, rubber grooves are fixedly connected to the upper end and the lower end of the side surface inside the adjusting inner groove, concave magnet blocks are uniformly and fixedly connected to the inside of the rubber grooves, a linking insertion block is fixedly connected to the middle position of the bottom of the adjusting driving rod and slidably connected to the inside of the adjusting inner groove, a convex magnet block is fixedly connected to the position, close to the right end, on the outer side of the linking insertion block, and corresponds to the concave magnet blocks, a track groove is formed in the position between the outermost side concave magnet block and the innermost side concave magnet block, the convex magnet block moves in the track groove, and the rubber grooves, the concave magnet blocks and, when the convex magnet piece is connected with the concave magnet piece in a matched mode, the stability is good, the phenomenon of easy sliding cannot occur when the cross screwdriver works, the anti-skidding cross-shaped tool bit mechanism is fixedly connected to the middle position of the bottom of the driving main rod, and the screw limiting mechanism is fixedly connected to the side face, close to the lower side, of the driving main rod. The driving main rod and the sectional type driving rod of the adjusting driving rod are adopted, so that the position of the cross screwdriver connecting rod can be flexibly adjusted according to the requirement of the environment, and the purpose of improving the using capacity of the cross screwdriver in a multi-space environment is achieved.

Furthermore, the position of the adjusting driving rod close to the upper part is provided with an auxiliary groove, and an auxiliary crowbar is clamped in the auxiliary groove. The auxiliary crowbar is arranged in the auxiliary groove, and after the position of the adjusting driving rod is adjusted, the cross screwdriver can twist the screw more easily.

Further, anti-skidding cross tool bit mechanism is including the installation center pillar, the top of installation center pillar and the intermediate position fixed connection of drive mobile jib bottom, the even fixedly connected with blade all around of installation center pillar, the blade is provided with four to the blade is the cross form and arranges, the even fixedly connected with in both sides surface of blade scrapes the curved strip of material. The scraping curved bars can scrape the rust slag or impurities in the cross groove, and the smoothness of the contact surface in the cross groove is ensured.

Further, the inside bottom of installation center pillar is run through and sliding connection has the pressure transfer line, the side that the installation center pillar is close to the below has evenly seted up the biography guide hole, move the slider in the top fixedly connected with that touches the pressure transfer line, move the inside sliding connection of removal slider and installation center pillar, the top of moving the slider passes through transmission spring and the inside fixed connection of installation center pillar, the equal fixedly connected with transmission taper plate in the outside both sides that are located the biography guide hole that moves the slider.

Furthermore, the inner side surface of the transmission conical plate is parallel to the surface of the blade, and the blade is in a triangular pyramid structure with a narrow upper part and a wide lower part.

Furthermore, the position of the blade close to the lower part is connected with a fitting fastening plate through a movable inserted bar in a sliding manner.

Further, the interior survey fixedly connected with drive taper plate of laminating mounting plate, the drive taper plate corresponds the setting with the transmission taper plate, the even fixedly connected with skid proof block of surface of laminating mounting plate. The clamping and fixing of the joint when the cross screwdriver is in extrusion contact with the screw are realized, and the phenomenon that the cross screwdriver slides and falls off when rotating is avoided.

Further, screw limiting mechanism is including the restriction track, restriction track and drive mobile jib surface fixed connection, restriction orbital inside sliding connection has the transmission slider, the top fixedly connected with of transmission slider stabilizes the spring, the outside fixedly connected with spacing pull rod of transmission slider, the firm splint of bottom fixedly connected with of survey in the spacing pull rod. Realize the stable joint of screw when twisting round and taking out, avoid the screw to drop.

Furthermore, the inner side of the stable clamping plate is fixedly connected with a limiting arc-shaped groove, and the inner part of the limiting arc-shaped groove is fixedly connected with a positioning thread. The purpose of stably preventing the screw from slipping while clamping the screw is achieved.

The working principle is as follows: the anti-skidding cross-shaped tool bit mechanism is inserted into the screw head, the blade is clamped with the cross-shaped groove in the screw cap and is pressed towards the direction vertical to the surface of the screw, and the screw can be twisted by rotating the handle; when the adjustable screw driver is used in a special space environment, the adjusting driving rod is moved transversely to avoid a barrier, the linking insertion block slides in the adjusting inner groove, so that the clamping position of the convex magnet block and the concave magnet block is driven to change, the magnetic force between the concave magnet block and the convex magnet block is mutually attracted until the adjusting driving rod moves to the outer side of the barrier, and the auxiliary crowbar is moved, so that the screwing of the screw can be realized; when the cross screwdriver is pressed downwards, the contact pressure transmission rod drives the inner moving slide block to move inwards and extrude the transmission spring, so that the transmission conical plate moves upwards to be in contact with the driving conical plate on the inner side of the fit fastening plate; when the cross screwdriver is matched and connected with the screw, the stable clamping plate is positioned on the outer side of the screw head, and the stable clamping plate is a good elastic plate, so that when the screw is screwed and lifted out, the arc-shaped groove is limited to be clamped below the screw head, the screw is ensured to be matched and stably extruded and contacted with the cross screwdriver under the action of the tension of the stable spring, the positioning thread is a thread pitch, and the positioning thread is matched and connected with the thread of the screw by adopting a rubber material, so that the stability is further realized; after the screw twists reverse the back, the extrusion force that upwards pulling cross screwdriver touched and pressed the transfer line disappears to the transmission taper plate separates with the drive taper plate, thereby the laminating mounting plate is not at the cross recess in the extrusion screw, and the screw breaks away from equipment under the joint of restriction arc wall simultaneously, and cross screwdriver drives the screw and stably breaks away from.
