Abstract

The utility model discloses an extensible hammer which belongs to the field of tools. The extensible hammer is convenient to carry and has wider adaptation surfaces due to the adjustable length of a handle of the hammer; the design of the extensible hammer is realized in the following manners that: the extensible hammer comprises a hammer head, the handle of the hammer which is connected with the hammer head is formed by the connecting of two sections of circular tubes with different thickness, wherein a pin rod penetrates through and is fixedly connected on the thick circular tube which is directly connected with the hammer head, i.e. on the pipe wall nearby the rear end of a pin pipe; a longitudinal sliding chute is machined on the thin circular pipe which is connected with the pin pipe, i.e. on the opposite pipe wall of a groove pipe; a blocking pin which comprises a blocking rod, a blocking pipe and a pressure spring is machined on the pipe wall of the front end of the groove pipe; and the pin pipe is connected with the groove pipe by the pin rod through the chute on the groove pipe.

Description

The stretching handle hammer

Technical field:

The utility model belongs to instrument apparatus field, specifically is meant hammer.

Background technology:

Hammer is to use wider a kind of impact tool, each family processing and other fields of still constructing is all bound, it is generally by hammer handle and tup two parts be combined into, tup is made into the moulding of various needs by ferrous material, hammer is then being one whole section round bar, sometimes be subjected to the narrow and small restriction in working environment space, this hammer is manipulated the hammer that is whole section not really smoothly, and the operator wishes to have a kind of hammer the into shape can the length wider a kind of hammer of adaptive surface that carries easy to adjust under concrete and complicated condition of work.

Summary of the invention:

The purpose of this utility model is the new technical scheme that a kind of hammer is provided, and it can address the above problem more effectively.

The technical solution of the utility model is to realize like this, it comprises tup, the hammer that is connected with tup is formed by connecting part by two sections thickness pipes, sell promptly near the rear end of pipe with the direct-connected thick pipe of tup wherein that the company of wearing is connected with pin rod on the tube wall, with mini diameter tube that the pin pipe connects is to be processed with vertical chute on the relative tube wall of barrel, chute is on the stage casing tube wall of barrel, be processed with the bayonet lock of being made up of kelly, card pipe, stage clip on the front end tube wall of barrel, pin rod will be sold pipe by the chute on the barrel and be connected with barrel.

The beneficial effects of the utility model are hammers can length easy to adjust carry and adaptive surface wider.

Description of drawings:

Fig. 1 is the front view of hammer.

Fig. 2 is the cutaway view of hammer.

Among each figure, 1 is tup, and 2 is the pin pipe, and 3 is bayonet lock, and 4 is pin rod, and 5 is barrel, and 6 is chute, and 7 is kelly, and 8 are the card pipe, and 9 is stage clip.

The specific embodiment:

Below in conjunction with accompanying drawing the design is briefly illustrated.

As Fig. 1, shown in Figure 2, promptly selling near pipe 2 the outer end on the tube wall in horizontal direction with tup 1 direct-connected thick pipe, the company of wearing is connected with pin rod 4, while is drilled with pin hole in vertical direction on the pin tube wall of the leftward position of pin rod, with mini diameter tube that the pin pipe connects is to be processed with vertical chute 6 on the relative tube wall of barrel 5, chute is on the stage casing tube wall of barrel and does not penetrate into two ends, on the front end tube wall of barrel, be processed with by kelly 7, card pipe 8, the bayonet lock 3 that stage clip 9 is assembled into, process the tube Cheng Kaguan 8 that a segment length is same as barrel 5 external diameters, the same cylinder of respectively packing at its two ends becomes kelly 7, the external diameter of kelly is slightly less than the internal diameter of card pipe, device has a stage clip 9 between two kellies, so just, be assembled into bayonet lock 3, bayonet lock is fixed on the tube wall of barrel front end, the kelly at two ends slightly protrudes from the tube wall periphery of pin pipe, as shown in Figure 1, pin rod 4 will be sold pipe 2 by the chute on the barrel 56 and be connected with barrel 5; Can stretch in the pin pipe from pin pipe external end head by the barrel that device is good, the kelly 7 that protrudes from barrel 5 tube walls by push just can flexible indentation pipe in, solid more dead the connection go up pin pipe 2 after again pin rod 4 being penetrated the chute 6 of barrel, this sample design civilian dress is put and is finished.Can be according to concrete needs, or the lengthening hammer outwards slides part by actuating barrel 5, the kelly 7 that the elasticity on the bayonet lock 3 supports outward can snap in the pin hole on the pin pipe 2, reaches the action effect of location; Shorten hammer part, reverse operation gets final product.

Claims

1. a stretching handle is hammered into shape, it comprises tup, it is characterized in that the hammer that is connected with tup is formed by connecting part by two sections thickness pipes, sell promptly near the rear end of pipe with the direct-connected thick pipe of tup wherein that the company of wearing is connected with pin rod on the tube wall, with mini diameter tube that the pin pipe connects is to be processed with vertical chute on the relative tube wall of barrel, chute is on the stage casing tube wall of barrel, be processed with the bayonet lock of being made up of kelly, card pipe, stage clip on the front end tube wall of barrel, pin rod will be sold pipe by the chute on the barrel and be connected with barrel.
