The first extension block and the second extension block are the same in shape, the orientation of the first extension block and the second extension block is adapted to a handle of the tube inserter, the first extension block and the second extension block are respectively arranged on the handle in a straddling mode and extend into the drawing slot, and then the fixing and clamping effects can be achieved.

Description

Fuse puller

Technical Field

The utility model relates to a fuse pulls out ware.

Background

The fuse includes a housing and an introducer having a handle thereon. When the circuit in the fuse is fused and the fuse needs to be maintained, the handheld part is held, the tube inserting device is vertically pulled upwards, the tube inserting device is separated from the shell, and the fusible core contained in the tube inserting device can be replaced. The existing extractor anthropomorphic dummy fingers adopt two clamping arms, and an extension block at the rear end of each clamping arm extends into a drawing groove from two sides of a lifting handle, so that a hand-held part can be lifted upwards. However, the existing puller does not design the extension block deeply, so that the extension block is difficult to smoothly penetrate into the drawing slot; even if the extension block protrudes into the drawing groove, it is difficult to adapt to the structure of the drawing groove of the fuse itself or the fitting operation with the adjacent fuse.

Disclosure of Invention

In view of this, the utility model aims at providing a simple structure, can adapt to draw groove and handle shape, regardless of the fuse puller that the direction of rotation all can realize accurate centre gripping intubate ware handle.

In order to realize above purpose, the utility model discloses a such fuse pulls out ware, including handheld portion, and by handheld portion drive first centre gripping arm and the second centre gripping arm of rotation on the plane, first centre gripping arm with second centre gripping arm extend first extension piece and second extension piece to the center respectively, the contact surface of first extension piece do the contact surface of second extension piece rotate 180 degrees on the plane around the central point. Compared with the prior art, the invention has the beneficial technical effects that: through the setting of above structure, the shape of first extension piece and second extension piece is the same, and orientation adaptation intubate ware's handle is striden respectively in the handle with first extension piece and second extension piece to stretch into and draw the groove, can realize the effect of fixed centre gripping.

In particular, the first clamping arm and the second clamping arm approach each other to the Y-axis, the first extension block and the second extension block each have a proximal end and a distal end, and the distance between the proximal ends is smaller than the distance between the distal ends. Through the arrangement of the structure, the handle takes the X axis as the axis, the middle part is narrow, the two ends are wide, the proximal end is suitable for acting on the central position of the handle, and the distal end is suitable for acting on the two end positions of the handle.

In particular, two inner peripheral edges of the first extension block and the second extension block are provided with edges which are matched with the width of the handle. Through the arrangement of the structure, the first extension block and the second extension block can be overlapped with the handle to effectively lift the action area when rotating regardless of the rotating direction.

In particular, the two peripheral edges of the first extension block and the second extension block are adapted to the shape of the corresponding adjacent handle. Through the arrangement of the structure, the clamping arms and the extension blocks at the rear ends can be conveniently inserted between the handles of the adjacent fuses.

Particularly, the handheld part is in a shape of a Chinese character 'yi'. Through the setting of above structure, compound staff operation custom on the one hand, on the other hand, the frame that is fit for hanging to put is connected out to handheld portion and the body of rod, conveniently receives and puts.

Particularly, the fuse opener further comprises a rod body perpendicular to the handheld portion and a base connected to the rod body, the upper plane of the base is parallel to the handheld portion, and the lower plane of the base is matched with a handle plane below the base. Through the arrangement of the structure, the base is prevented from being blocked by the components such as the handle and the like in the rotating process.

Detailed Description

As shown in fig. 1 to 6, a fuse puller comprises a handheld portion 1, and a first clamping arm 41 and a second clamping arm 51 which are driven by the handheld portion 1 to rotate on a plane, wherein the first clamping arm 41 and the second clamping arm 51 extend out of a first extending block 4 and a second extending block 5 to the center respectively, and a contact surface of the first extending block 4 is a contact surface of the second extending block 5 which rotates 180 degrees on the plane around a central point.

The first holding arm 41 and the second holding arm 51 approach each other to the Y axis, and the first extension block 4 and the second extension block 5 each have a proximal end and a distal end, and the distance between the proximal ends is smaller than the distance between the distal ends.

The two inner peripheral edges of the first extension block 4 and the second extension block 5 have edges corresponding to the width of the handle a 2.

The two peripheral edges of the first extension block 4 and the second extension block 5 are adapted to the shape of the corresponding adjacent handle a 2.

The hand-held part 1 is in a shape of Chinese character 'yi'.

The fuse opener further comprises a rod body 2 perpendicular to the handheld portion 1 and a base 3 connected to the rod body 2, the upper plane of the base 3 is parallel to the handheld portion 1, and the lower plane of the base 3 is matched with a lifting handle A2 plane below the base 3.
