Abstract
The utility model provides a hammer which belongs to tools and is mainly used for solving the problem that fingers are easily injured by driving nails on walls. The hammer comprises a base, a hammer part, a spring, connecting rods and a digging rope, wherein a horizontal rotating shaft is arranged on the lower part of the base, the base is movably connected with the tail end of a hammer handle through the rotating shaft, a horizontal rotating shaft is arranged in the middle of the base, the base is movably connected with one ends of the connecting rods through the rotating shaft, a horizontal breach is formed in the top of the base, and a spring is arranged between the base and the hammer handle; and a horizontal rotating shaft is arranged in the middle of the hammer handle, the hammer handle is movably connected with one ends of the connecting rods through the rotating shaft, the free ends of the connecting rods are movably connected together through the rotating shaft, and the digging rope is arranged on the rotating shaft. The hammer has the advantages that injury caused by driving nails is avoided by fixing the nails in the breach, a four-link mechanism with a mid-gear is adopted, and the knocking process of the hammer is finished through stored force of the spring, so that the operation difficulty of users is reduced.
Description
Technical field
The utility model relates to a kind of instrument, specifically a kind of hammer.
Background technology
Hammer is a kind of common tool of nailing, when using hammer when vertical wall is nailed, because operation posture is limit, the user is difficult to hold the nail of waiting to be driven into wall, and in operating process, hammer is pounded partially easily, injures the finger that the user is pinching nail by a crashing object.
The utility model content
The purpose of this utility model is to provide a kind of hammer, and mainly solving nails at wall is injured by a crashing object the problem of finger easily by hammer.
The technical scheme in the invention for solving the technical problem is: a kind of hammer, its structure comprises base, hammer, spring, connecting rod and stay cord, described base bottom and middle part respectively are provided with a horizontal rotating shaft, base flexibly connects with the end of hammer handle and an end of connecting rod respectively by rotating shaft, the top of base is provided with the gap of a level, is provided with a spring between base and the hammer handle; The middle part of described hammer handle is provided with a horizontal rotating shaft, and hammer handle flexibly connects by an end of this rotating shaft and connecting rod, and the free end of described two connecting rods flexibly connects by rotating shaft, and this rotating shaft place is provided with a stay cord; The arc of movement track of the cut-out direction of described gap and tup is tangent.
Described two connecting rods bend downwards around the rotating shaft that it joins, and two connecting rods are its dead-centre position when the conllinear state.
The beneficial effects of the utility model are: adopt nail is fixed on structure in the gap, avoid the user to pinch nail with pointing, avoid injuring by a crashing object.Employing is provided with the four-bar mechanism of dead-centre position, holds the process of knocking that power is finished hammer by spring, reduces user's operation easier.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 gap, 2 nails, 3 bases, 4 springs, 5 tups, 6 hammer handles, 7 rotating shafts, 8 rotating shafts, 9 connecting rods, 10 connecting rods, 11 rotating shafts, 12 stay cords, 13 rotating shafts, 14 walls.
The specific embodiment
As shown in Figure 1.A kind of hammer, its structure comprises base 3, tup 5, spring 4, connecting rod 9, connecting rod 10 and stay cord 12, the bottom of described base 3 is provided with the rotating shaft 13 of a level, base 3 flexibly connects by the end of rotating shaft 13 with hammer handle 6, the middle part of base 3 is provided with the rotating shaft 7 of a level, base 3 flexibly connects by the end of rotating shaft 7 with connecting rod 9, the top of base 3 is provided with the gap 1 of a level, be provided with a spring 4 between base 3 and the hammer handle 6, tup 5 and gap 1 near the time, spring 4 is in free state; The middle part of described hammer handle 6 is provided with the rotating shaft 8 of a level, and hammer handle 6 flexibly connects by the end of rotating shaft 8 with connecting rod 10, and the free end of described connecting rod 9 and connecting rod 10 is movably connected by rotating shaft 11, is provided with a stay cord 12 in the position of rotating shaft 11; Described two connecting rods are merely able to bend downwards around its rotating shaft of joining, and two connecting rods are its dead-centre position when the conllinear state.The arc of movement track of the cut-out direction of described gap 1 and tup 5 is tangent.
During use, in the gap 1 with nail 2 placements, with hand propelled connecting rod 9 and connecting rod 10, make its conllinear, the four-bar mechanism of connecting rod 9, connecting rod 10, base 3 and hammer handle 6 required formation is in the dead point state at this moment, though the spring 4 that is stretched imposes on the active force of hammer handle 6 resiliences, it is stable that four-bar mechanism still can keep; The user lifts base 3 and leans against on the wall 14, pull stay cord 12 then, the active force that stay cord 12 is applied to rotating shaft 11 makes four-bar mechanism lose stable and the disengaging dead-centre position, the pulling force of spring 4 discharges and pulling hammer handle 6 13 is drawn close to base 3 around the shaft, and drive tup 5 and impact on nail 2, realize to nail 2 function of wall 14.
Claims (2)
1. hammer, it is characterized in that, its structure comprises base, hammer, spring, connecting rod and stay cord, described base bottom and middle part respectively are provided with a horizontal rotating shaft, base flexibly connects with the end of hammer handle and an end of connecting rod respectively by rotating shaft, the top of base is provided with the gap of a level, is provided with a spring between base and the hammer handle; The middle part of described hammer handle is provided with a horizontal rotating shaft, and hammer handle flexibly connects by an end of this rotating shaft and connecting rod, and the free end of described two connecting rods flexibly connects by rotating shaft, and this rotating shaft place is provided with a stay cord; The arc of movement track of the cut-out direction of described gap and tup is tangent.
