[0032] Please refer to Figures 1 to 5 Example one:

[0033] The embodiment proposes a portable engineering cost manual labor time recording device, which comprises a fingerprint attendance machine 1 and a supporting mechanism, and the supporting mechanism comprises a U-shaped support frame 3 and a U-shaped positioning frame 301.

[0034] The U-shaped positioning frame 301 is slidingly installed on the U-shaped support frame 3 and is positioned by a spring; the U-shaped support frame 3 is rotationally connected to the top end of the fingerprint attendance machine 1; four positioning holes 102 are symmetrically formed in the top end of the fingerprint attendance machine 1; two longitudinal insertion rods of the U-shaped positioning frame 301 are selectively inserted into the four positioning holes 102; two day-shaped sleeves 302 are symmetrically welded at the two ends of the transverse side rod of the U-shaped positioning frame 301; the two day-shaped sleeves 302 are slidingly matched with the two longitudinal side plates of the U-shaped support frame 3; two strip-shaped grooves 303 are formed in the two longitudinal side plates; two track shafts 304 are fixedly connected in the two strip-shaped grooves 303; the middle connecting block of the two day-shaped sleeves 302 is slidingly matched with the two track shafts 304 and the two strip-shaped grooves 303; the spring that positions the U-shaped positioning frame 301 is sleeved on the track shaft 304 and is compressed and clamped between the tail end of the strip-shaped groove 303 and the middle connecting block of the day-shaped sleeve 302.

[0035] Preferably, two installation grooves 103 are symmetrically formed in the top end of the fingerprint attendance machine 1; and two hinge shafts 1031 are welded in the two installation grooves 103.

[0036] Preferably, the four positioning holes 102 are arranged in two groups and are arranged on the top end of the fingerprint attendance machine 1 and the top end of the back side of the fingerprint attendance machine 1.

[0037] In the second implementation, the following content is added compared with the first implementation:

[0038] The strip-shaped cover plate 2 is rotationally installed on one long side of the shell of the fingerprint attendance machine 1; a vertical groove 101 is formed on the long side near the tail end of the strip-shaped cover plate 2; a transmission short rod 201 is vertically welded at the tail end of the strip-shaped cover plate 2; the transmission short rod 201 is swingingly moved in the vertical groove 101; and a tension spring 202 is obliquely hung between the top end of the vertical groove 101 and the head end of the transmission short rod 201.

[0039] Preferably, the long side of the fingerprint attendance machine 1 is provided with a circular charging port 4 and a USB communication port 5 in an upper and lower spaced manner.

[0040] Preferably, the strip-shaped cover plate 2 is closed and covers the circular charging port 4 and the USB communication port 5.

[0041] The working principle, specific details, implementation steps, functions and mutual relationships of the features, and the role in the implementation of the application are described and explained in detail as follows:

[0042] The U-shaped support frame 3 is installed by rotation. When it is positioned perpendicular to the back side of the fingerprint attendance machine 1 (refer to...), Figure 1 The U-shaped support frame 3 can support and lift the fingerprint attendance machine 1 when it is lying down, so that the fingerprint attendance machine 1 can be stably kept in an inclined position, so that workers can press their fingerprints to clock in and out. When the U-shaped support frame 3 is positioned in a state perpendicular to the top of the fingerprint attendance machine 1, it can be used as a handle for lifting and transferring the fingerprint attendance machine 1. Thus, the U-shaped support frame 3 can serve as both an inclined support mechanism for the fingerprint attendance machine 1 and a handle for the fingerprint attendance machine 1, which has a dual-purpose function. This function eliminates the need to configure additional handles or other lifting components for the fingerprint attendance machine 1, which helps to simplify the structure of the fingerprint attendance machine 1, and is conducive to the miniaturization of the fingerprint attendance machine 1 and can improve the portability of the fingerprint attendance machine 1.

[0043] When the two vertically placed rods of the U-shaped positioning bracket 301 are inserted into the four positioning holes 102, the U-shaped support frame 3 can be maintained in the two usage states mentioned above.

[0044] The springs on the two track shafts 304, which are used to push and position the U-shaped positioning frame 301, are completely concealed in the strip groove 303. This avoids the two springs from being directly exposed to the U-shaped support frame 3 and suffering excessive wear from external objects, thus helping to extend the service life of the two springs.

[0045] When it is necessary to verify workers' working hours during the project cost estimation process, the USB communication port 5 needs to be connected to the computer via a USB data cable to read the attendance data stored inside the fingerprint attendance machine 1.

[0046] When the fingerprint attendance machine 1 is not charging or not reading attendance data, the strip cover 2 can close and seal the circular charging port 4 and USB communication port 5. This prevents a large amount of dust from the external environment from entering the circular charging port 4 and USB communication port 5, causing them to malfunction. This makes the fingerprint attendance machine 1 suitable for dusty construction work conditions. The strip cover 2 can be pulled and sealed to the circular charging port 4 and USB communication port 5 via the transmission rod 201 and the tension spring 202. The tension spring 202 and the transmission... The short rod 201, which is used to pull and seal the strip cover 2, is completely concealed inside the vertical groove 101. This prevents it from protruding from the fingerprint attendance machine 1 housing and increasing the size of the fingerprint attendance machine 1, which helps to further miniaturize the fingerprint attendance machine 1 and also further improves the portability of the fingerprint attendance machine 1. When charging or reading attendance data through the circular charging port 4 and USB communication port 5, simply flip the strip cover 2 up to expose the circular charging port 4 and USB communication port 5.
