Abstract
The utility model relates to a knife, in particular to a novel pin lock jackknife which comprises a knife body and a knife scabbard. The knife body and one end of the knife scabbard are connected in a hinged mode through a rotary shaft. The novel pin lock jackknife is characterized in that a first notch is formed in a knife back side of the connection between the knife body and the knife scabbard, a second notch is formed in a knife edge side of the connection between the knife body and the knife scabbard, a first clamping groove is formed in the upper portion of the connection between the knife body and the knife scabbard, a pin is arranged in the first clamping groove, and corresponds to the first notch and the second notch, the pin is connected with a spring, one end of the spring is fixed on the knife scabbard, a second clamping groove is formed at the top end of the connection between the knife scabbard and the knife body, a reversely-triangular hand-pushing portion is arranged in the second clamping groove, and the lower portion of the hand-pushing portion is sleeved on the pin. According to the novel pin lock jackknife, a pin locking mechanism and the hand-pushing portion are combined, the novel pin lock jackknife is light and labor-saving when being opened, is firm in locking after being opened, and cannot easily hurt people when being used for cutting with large force.
Description
Technical field
The utility model relates to a kind of cutter, especially a kind of novel pin lock jackknife.
Background technology
Existing jackknife mostly is to adopt the pin locking mechanism to realize folding and opening of cutter.Existing pin locking mechanism is made up of pin and spring, and when jackknife was in folded state, cutter hub was recessed in the sheath, and pin will be pushed open pin and need be used bigger strength by locking; When jackknife was in open mode, when using bigger power during the cutting thing, cutter hub was folded up again easily, and the user is easily injured.
The utility model content
For addressing the above problem, the utility model provides a kind of novel pin lock jackknife, open easily, and locking firmly is difficult for hurting sb.'s feelings when folding.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
A kind of novel pin lock jackknife, comprise cutter hub and sheath, described cutter hub and sheath one end are hinged by rotating shaft, it is characterized in that: the knife back of the junction of described cutter hub and sheath and blade side are provided with first recess and second recess, the top, junction of described sheath and cutter hub is provided with first draw-in groove, be provided with and first in described first draw-in groove, the pin of the second recess correspondence, described pin is connected with spring, described spring one end is fixed on the sheath, the top of described sheath and cutter hub junction is provided with second draw-in groove, be provided with the pushing hands of del in described second draw-in groove, the bottom of described pushing hands is sheathed on the pin.
Stir the pushing hands in second draw-in groove, pushing hands drives pin mobile meeting holddown spring in first draw-in groove, and when pin shifted out first recess, cutter hub just can rotate freely and be folded into sheath, thereby pin enters second recess locking pin under the screen resilience effect of spring, the clawback pushing hands further locks again.In the time of need opening jackknife, stir the pushing hands in second draw-in groove again, pushing hands drives pin mobile meeting holddown spring in first draw-in groove, when pin shifts out second recess, cutter hub easily can be pulled out sheath, when cutter hub launches fully, thereby pin enters first recess locking pin under the screen resilience effect of spring, and the clawback pushing hands further locks again.
Further, the described first recess length is greater than second recess.When jackknife was opened, second recess was shorter, easier first draw-in groove that shifts out of pin, and when cutting energetically after opening, first recess is longer, and pin is difficult for shifting out first draw-in groove, locks more firm.
The utlity model has following beneficial effect: light laborsaving when jackknife is opened, open the back locking firmly, also be difficult for when cutting energetically hurting sb.'s feelings.
Description of drawings
Fig. 1 is the structural representation of the utility model when opening;
Fig. 2 is the structural representation of the utility model when folding;
Wherein 1 is cutter hub, the 2nd, pin, and 3 is first recesses, the 4th, pushing hands, the 5th, spring, 6 is first draw-in grooves, the 7th, sheath, 8 is second recesses.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
Embodiment 1: novel pin lock jackknife as shown in Figure 1, comprise cutter hub 1 and sheath 7, cutter hub 1 and sheath 7 one ends are hinged by rotating shaft, cutter hub 1 is provided with first recess 3 and second recess 8 with the knife back and the blade side of the junction of sheath 2, the length of first recess is greater than the length of second recess 8, sheath 7 is provided with first draw-in groove 6 with the top, junction of cutter hub 1, be provided with and first in first draw-in groove 6, the pin 2 of the second recess correspondence, pin 2 is connected with spring 5, spring 5 one ends are fixed on the sheath 7, sheath 7 is provided with second draw-in groove with the top of cutter hub 1 junction, is provided with the pushing hands 4 of del in second draw-in groove, and the bottom of pushing hands 4 is sheathed on the pin 2.
Operation principle of the present utility model: stir the pushing hands 4 in second draw-in groove, pushing hands 4 drives pin 2 mobile meeting holddown spring in first draw-in groove 6, when pin shifts out first recess 3, cutter hub 1 just can rotate freely and be folded into sheath 7, thereby pin 2 enters second recess, 8 locking pins 2 under the screen resilience effect of spring 5 then, and clawback pushing hands 4 further locks again.In the time of need opening jackknife, stir the pushing hands 4 in second draw-in groove again, pushing hands 4 drives pin 2 mobile meeting holddown spring 5 in first draw-in groove 6, when pin 2 shifts out second recess 8, cutter hub 1 easily can be pulled out sheath 7, when cutter hub 1 launches fully, thereby pin 2 enters first recess, 3 locking pins 2 under the screen resilience effect of spring 5, and clawback pushing hands 4 further locks again.Because the length of first recess 3 is greater than the length of second recess 8, when jackknife was opened, second recess 8 was shorter, pin 2 easier first draw-in grooves 6 that shift out, and when cutting energetically after opening, first recess 3 is longer, and pin 2 is difficult for shifting out first draw-in groove 6, locks more firm.
