[0021] The utility model provides a PDA that is easy to hold, including a support bar 101, a PDA body 102, a connecting plate 104, an adjustment component, a pull handle 105 and a grip 106, wherein the adjustment component includes an insertion bar 107, a plurality of blocking bars 108, a shell 109, a housing 110, a pull rod 111, a spring 112, a ring 113 and a limit bar 114, the PDA body 102 is provided with a plurality of arranged and distributed grooves 115, and the limit bar 114 is provided with a chamfered surface 103.

[0022] According to the present specific embodiment, the user passes the hand through the support bar 101, and then pulls the pull rod 111 to disengage the limit bar 114 from the insertion bar 107 and the corresponding stop bar 108, and then pulls the insertion bar 107 to move, thereby adjusting the tightness of the support bar 101. After the adjustment is completed, the pull rod 111 is released, and under the elastic force of the spring 112, the limit bar 114 is pushed back to the original position, and is again abutted against the insertion bar 107 and the corresponding stop bar 108, thereby limiting the support bar 101 and preventing the device from falling off the user's hand. In this way, the device can adjust the tightness of the support bar 101, which is convenient for users with different hand sizes to use and avoid detachment. When the user's arm passes through the support bar 101 When the user's fingers are adapted through the multiple grooves 115, the user can comfortably place his hand between the PDA body 102 and the support bar 101. The setting of the pull handle 105 makes it convenient for the user to pull the pull rod 111 through the pull handle 105 to move. When the tightness of the support bar 101 needs to be adjusted, it is only necessary to pull the grip 106 to drive the insertion bar 107 to move, so that the corresponding blocking bar 108 squeezes the chamfered surface 103, thereby pushing the limit bar 114 to move, so that the tightness of the support bar 101 is tighter. After the insertion bar 107 is moved, under the elastic force of the spring 112, the limit bar 114 will return to its original position again and be pressed against the corresponding blocking bar 108 for limit.

[0023] The connecting plate 104 is fixedly connected to the right end of the PDA body 102, the shell 109 is fixedly connected to the right end of the PDA body 102 and is located below the connecting plate 104, one end of the support bar 101 is fixedly connected to the connecting plate 104, the other end of the support bar 101 is fixedly connected to the insertion bar 107, the insertion bar 107 passes through the shell 109, and the plurality of blocking bars 108 are respectively arranged at the right end of the insertion bar 107 and are respectively located inside the shell 109. The shell 110 is fixedly connected to the right end of the shell 109, one end of the pull rod 111 passes through the shell 110 and the shell 109, and is fixedly connected to the limit bar 114, the limit bar 114 abuts against the right end of the insertion bar 107 and contacts the corresponding baffle bar 108, the ring 113 is fixedly sleeved on the outside of the pull rod 111 and is located inside the shell 110, and the two ends of the spring 112 are fixedly connected to the inner wall of the shell 110 and the ring 113 respectively. The user passes his hand through the support bar 101, and then pulls the pull rod 111 to disengage the limit bar 114 from the insertion bar 107 and the corresponding baffle bar 108, and then pulls the insertion bar 107 to move, thereby adjusting the tightness of the support bar 101. After the adjustment is completed, the pull rod 111 is released, and under the elastic force of the spring 112, the limit bar 114 is pushed back to the original position, and again abuts against the insertion bar 107 and the corresponding baffle bar 108, thereby limiting the support bar 101 and preventing the device from falling off the user's hand. The device can thus adjust the tightness of the support bar 101, making it convenient for users with different hand sizes to use and avoiding detachment.

[0024] Secondly, the PDA body 102 has a plurality of arranged and distributed grooves 115. When the user's arm passes through the support bar 101, the plurality of grooves 115 are adapted to the user's fingers, so that the user can comfortably place his hand between the PDA body 102 and the support bar 101.

[0025] At the same time, the pull handle 105 is fixedly connected to the pull rod 111 and is located at the right end of the pull rod 111. The arrangement of the pull handle 105 facilitates the user to pull the pull rod 111 through the pull handle 105 to move.

[0026] In addition, the limit bar 114 has a chamfered surface 103, and the handle 106 is fixedly connected to the insertion bar 107 and is located at the lower end of the insertion bar 107. When the tightness of the support bar 101 needs to be adjusted, the handle 106 is simply pulled to drive the insertion bar 107 to move, so that the corresponding blocking bar 108 presses the chamfered surface 103, thereby pushing the limit bar 114 to move, so that the tightness of the support bar 101 is tighter. After the insertion bar 107 moves, the limit bar 114 will return to its original position again under the elastic force of the spring 112, and abut against the corresponding blocking bar 108 for a limit position.

[0027] When using the PDA that is easy to hold of the utility model, the user passes the hand through the support bar 101, and then pulls the pull rod 111 to disengage the limiting strip 114 from the insertion strip 107 and the corresponding blocking strip 108, and then pulls the insertion strip 107 to move, thereby adjusting the tightness of the support bar 101. After the adjustment is completed, the pull rod 111 is released, and under the elastic force of the spring 112, the limiting strip 114 is pushed back to the original position, and is again abutted against the insertion strip 107 and the corresponding blocking strip 108, thereby limiting the support bar 101 and preventing the device from falling off the user's hand. In this way, the device can adjust the tightness of the support bar 101, which is convenient for users with different hand sizes to use and avoid detachment. When the user's arm passes through the support bar 101, the plurality of grooves 115 are adapted to the user's fingers, so that the user can comfortably place his hand on the support bar 101. The setting of the pull handle 105 between the PDA body 102 and the support bar 101 makes it convenient for the user to pull the pull rod 111 through the pull handle 105 to move. When the tightness of the support bar 101 needs to be adjusted, the grip 106 only needs to be pulled to drive the insertion bar 107 to move, so that the corresponding blocking bar 108 squeezes the chamfered surface 103, thereby pushing the limit bar 114 to move, thereby making the tightness of the support bar 101 tighter. After the insertion bar 107 is moved, under the elastic force of the spring 112, the limit bar 114 will return to its original position again, and be pressed against the corresponding blocking bar 108 for limit. The device has multiple intelligent inventory functions. When the bar code of the product is close to the PDA body, it can be automatically scanned and shipped out, reducing manual operations. It can scan and read multiple bar code labels at the same time to improve scanning efficiency. It is also small in size and easy for users to hold.
